Application filed August 14, 1905. Serial No. 274,123.

.To (LZ/ whom t my'conccrn Be it known that I, JAMES H. SWArN, .a

citizen of the United States of America, re-' ticdlarly' to tires for automobiles sind motor' driven vehicles.

The object ol" this invention is to provide a.

1 non-penetrable end non-leakeble tire which will withstand the rough usuage to which it is subjected.

Another object of this invention is to provide u. tire wherein novel kinds of material zo are employed for strengthening, supporting, and. adding rigidity to the' tire, particularly the ti'ecd'portion thereof7 which. is eX osed to the weer and teur when the tire is eiligr used.

A further object of this invention is to provide :i tire-of :t resilicntnature capable of o,

holding cir under high pressure, thus forming' c. pneumatic cushion-tire that is ccpubleoi 'forining a cushion for e. vehicle supported by 3o the tires constructed in accordance with my invention With the above and other objects in View the invcn tion consists in the novel construction, combination, and errengement of perts 35 to be ,hereinafter more fully described end then snecificelly ointed out in the claims, und, relerring to t e drawings accompanying this application, like numerals of reference designate correspondingv parts throughout 4o theseverel views, vin Which-- Figure 1 is e. cross-sectional view of my improved tire. Fig. Zie a plein of a. portion of the tire, illustretingthe various layers of .materiel used in 'thc-construction of the tire.

45' Fig. 3 is c detail perspective view of a portion of s. strip of meteriel employed to strengthen the'tire. 4 is s.-crossse`actional view of a strip o'strengthening material, illustrating s. modified form of construction.

5o The present invention, like those in compenion epplicetions, Seriel Nos.'271,182 and 271,183, involves the use of vulcanized fiber es one of the constituent, elements in the erung-rib, which is employed structure oi the tire. In this invention there is employed in connection with. the fulminized ber ribbon-like strips of metal (prefercblysteel) which ribbon-like strips of metal are faced on both sides with the vulccnized ber.

I am aware that it has heretore been proposed to employ these ribbon-like strips of steel in n. pneumatic tire, und since the action of thc rubber in the tire on the steel hes s. tend-- ency to socle the steel it has been proposed to cover the strips of `steel with e. tebric mete.n 65 rial. However, various defects lieve been 'found in tires so constructed in that the cover-- ings en'ipioyed heretofere 'or the steel strips were either in themselves liable to thedeterioruting action of the rubber, or if of inneture 7o to resist such action of the rubber they lied n. tendency to destroy the reeuired resiliency of the tire, and ere further defective in that the frictionel contuict between tbe'covering material und the steel usuelly tends to cause 7 5 the rapid destroying ci the covering materiel to the detriment ofA the tire .es e Whole and rendering it ineffective for the purpose desired.

By the employment of vulcanized ber 8o a facing or covering for the steel strips l'heve discovered en effective combination of mate ricls, the vulcanized iher eiectuelly protect ing the steel stripe from the deteriorgiting fiction of the rubber und the vulcanized r'iber 85 in itself being in no wise effected by the ruhber in contact therewith. Furthermore, the resiliency oi these 'two particule-r .materials appears in practice to have e. peculiar siiinity,

es the desired resiliency in the tire is bi no ,9o. Ineens impaired, but 'ies in practice een demonstrated that it is improved.

. To put my invcnticninto practice, Leon` Struct my improved tire of an inner cir-tube 1, which ispreferehly puede of robber, and 95 surrounding this ei1 -tube is e. layer or wrapping;r of fabric 2, such es canvas or like meterial. ln connection with my improved tire I emplo strengtheningetrips 3, which are ar range within'the tire-longitudinally of its length, thereby forming t. peripheral strengtl1- urticularlv upon the side of the tire used or e treed. Each strengthening-strip consists of e piece of thin resilient steel 4, and secured to eecli side of this piece of steel ere pieces of vulcan l'and upon this side of the fabric Wrapping or 'layer oi canvas 12 or like material surrounds ized fiber 5 5, which may.' be secured to the piece of steel bysewing the three* pieces of material together, the stitches being repre lsented in Fig. 3 of the drawings and designated 6. In Fig. 4 of the drawings I beve illustrated another manner o securing theY three pieces of material together, which con-- sists oi' surrounding a piece osreei e and thvuloanizei'l pieces of ber 5 5 with e piece of canvas or like fabric 5', this fabric being adapted to hold the three pieces together.

In Ifig. 1 ot' the draWines the side of the .ft-ire which forms the tread is designa-.ted .7,

layer Z I have shown four of the strengthening-strips 3 3 3 3, and betweenv these strips I rrange the strips of rubber 8, these strips of rubber being arranged iongitudinally of the length of' the tire, similar to the strengthening-strips The striY s of rubber and the st-rengthenirig-strips are then surrounded by i1- l'ebric wrapping' or lsyer of canvas 9, and upon this Fabric Wrapping are arranged three sLrengthening-strips 1() 10 10, said strips being arranged directly above the rubber Strips S, interposeiii between the strengtheningstrips 3. The strenfthening-strips- 1D are similar to the strengthening-strips 3 and between toe strips l() 'I arrange the rubber strips 1 1, similar to the rubber strips 8. A

the strips 10 and 11, as clearly illustrated in Figs. 1 and 2 of the drawings.

Two strengtheningstrips 14 Y14, similar to the strips and i0, are arranged upon the fabric wrapping 12, and these stri. s 14 cover the rubber' strips i1, interpose between the strips i() i0. A strip of rubber v15 is nic-unted between tbe strengthening-strips..1@ i4, an d those. strips covered With s canvas or fabric wrapping 16. Upon this Wrapping is mounted a. strengtheningstrip 17, sirniiar 'to the strips 3, 1U, and 14, this strip being arranged above the rubber strips ,15, interposed between the strips 1li le. In forming the wreppings in complete y the strengtheningstrips canvas or fabric material-- 18 is ernployed, and the tires so lcr formed are provided with three wrappngs of fabric, such as :auras 1Q, and inclosing these wrappings and the tire construction vinst described is an outer tube 2), having an enlarged tread portion 11, this outer tube being preferably confl simu-led ol' rubber.

ly the construction ol" my improved tire it will be observed that the stavffcred arrangeme munt ol the '.i'iegtliening-strips or the. tire provides a foundation For the trend oi" the tire, this foundation being.; established in close proxil'nity to the inner eer-tube and terminating neer the periphery of the tire. "llie arrangement of the strengtlieningfstrins, es gicoelly their ov .Mapped or lujo ioints, i'lorms v a non-penetrahie .vali between the periphery ol the tire end toe inner air-tube, :it the saine l time strengthening'the inner aintnbe when air is forced into tne seme under pressure;

The arrangement of the strcngtheningetrips nermits of the tire being depress-ed Without coila the same, and it will be im ossible for Le diderent parts of myimprove tire to become 'disarranged when they have been thoroughly 'Wrapped with the fabric hereto-` fore described. f

I desire to callparticular attention to the a parent aiinity between the vulcanized" er as afecin materiel and the ribbon-hire strips of metan, as heretofore steted. The vulcanized ber being initseir a Insteral which is vextremely herd to puncturel formso facing which is not liable to become rough, and thus'it ispossibie that a smooth ieee or .the vuleenized-iiber strips is abmiys 'presentn e'd to the face of the steel strips, causing ne undue friction' between these' two materieis in case of an f movement of the seme with respect to eac 1 other. The rubber' having no effect on the vulcanized fiber, a structure is produced which remains substantially intact in its originel form until the tread of the tire has been Worn out.

i I do not' ner of asseinii i strengthenin -rios or to the particular rangernent o these ribs as illustrated in the i 1.1 cantine ing/*sebi to the nienn ne different parts of? the acconipanyinff drawings, it being nnderstoed. i

that Various c may be made in the details of construction without deperting from the s irit and scope of the invention.
